This embodiment discloses an automatic bit placing device, as Figure 1As shown in the figure, it includes a tray placing frame 1, a tray placing controller and a tray placing air pump arranged inside the tray placing frame 1. A bit feeding mechanism 2, a spider hand mechanism 3 and a transfer tray placing mechanism 4 are provided on the tray placing frame 1 and are adapted to each other. The bit feeding mechanism 2 is used to feed the bits to be placed in the bit box. The spider hand mechanism 3 is used to pick up the bits in the bit feeding mechanism 2 and transfer them to the transfer tray placing mechanism 4.

[0041] As Figure 1 shown, the bit feeding mechanism 2 includes a flexible vibrating disk 21 and a number of linear feeders 22 adapted to the flexible vibrating disk 21. A number of bit storage boxes 23 adapted to the linear feeders 22 are arranged on the flexible vibrating disk 21.

The lifting buffers 4115 on both sides of the cylinder 4114 have piston rods that are arranged upwards, and the lifting buffers 4115 cooperate with the lifting cylinder 4114 to achieve a buffering effect. A plurality of lifting optical axes 4116 that are compatible with the rotating structure 412 are also interspersed on the lifting top plate 4111. The lifting optical axes 4116 and the upper ends of the piston rods of the lifting cylinders 4114 are fixedly connected to the rotating bottom plate 4121.

The rotating part is provided with a rotary arc edge 4123a and a rotary straight edge 4123b respectively adapted to the rotary arc groove 4124a and the limiting straight edge 4124b. The two rotary straight edges 4123b are arranged in parallel. The cooperation between the rotary arc groove 4124a and the rotary arc edge 4123a facilitates the rotation of the rotating arm 4123. The cooperation between the limiting straight edge 4124b and the rotary straight edge 4123b facilitates the reciprocating rotation of the rotating arm 4123 towards the bit transfer assembly 42 and the bit box to achieve the material taking and placing actions. Two rotary buffers 4125 adapted to the rotating arm 4123 are horizontally penetrated on the limiting plate 4124. The piston rod of the rotary buffer 4125 faces the side of the rotating arm 4123.
